11 Claims.

This invention relates to a mechanism for producing headgear of the typeused by chefs, waiters, bakers and storekeepers. Usually if suchattendants wear caps, they are formed of fabric, such-as linen, whichmust be laundered frequently to maintain them in a sanitary andneat-appearing condition. This repeated cleansing causes the caps toprematurely deteriorate and they must therefore be replaced withinrelatively short periods. 'Because of the expensiveness of theserequirements, the use of such caps has not be come as widespread as itmight have otherwise.

An object of this invention resides in the provision of a machine whichwill produce caps of the type mentioned from relatively inexpensivesheet or strip material in order that the caps may be discarded whenthey become soiled. Caps so produced are similar in appearance to thelinen caps but because of their low cost, due to their manner ofproduction and discardability, they become more desirable.

The machine forming the present invention comprises an improvement overthat disclosed in the patent to Glenn A. Shafier et al., No. 2,023,152dated December 3, 1935, whereby the practicability, efiiciency andproductivity of the machine is increased and the degree of personalattention required to maintain the machine in proper operating conditiondiminished.

It is an object of the invention to provide a cap-making machine havinga series of sets of rollers operated by power driven means to unwind astrip of paper from a supply roll; emboss the paper to cause it tosimulate fabric; print advertising or other indicia thereon; waterproofa longitudinally extending zone of reduced width on the strip; form aplurality of longitudinally extending creases in the strip; successivelysever sections of predetermined length from the strip and feed thesesections to mechanism provided on the machine which will operate on thestrip sections to roll and fold the same into collar-like band-formingbodies, additional means cooperating with the last named mechanism toapply sheets of thin paper to the bodies to close one end of each andform the crowns of the finished caps. An object also resides inproviding means ad" jacent to certain of the sets of rollers, mentionedabove, to apply color and designs to the paper passing between therollers, means being provided to mount the color and design applyingmeans on the machine in such manner that they may be readily moved intoand out of operating positions.

,Another object resides in providing the strip rolling and foldingmechanism with a turret head having a plurality of mold chamberscircumferentially spaced thereon, means being provided to intermittentlymove the turret head to successively register the mold chambers withapparatus for inserting the strip sections into the chambers, performingvarious operations on the strip sections while they are disposedwithinthe chambers and discharging the caps from the turret, the turret movingmeans being so designed as to facilitate the smooth, rapid productionoi'caps and reduce to a minimum the attention required to keep themechanism in operating condition.

A further object rests in providing improved mechanism for introducingthe crown forming sheets to the molds containing the partially foldedstrip sections, the sheet introducing mechanism having roller means forwithdrawing paper from a supply roll, knife means for cutting the paperinto proper size pieces; means for positioning these pieces inregistration with a mold chamber while maintaining them in a flatcondition; and means for moving the pieces into the mold at the propertime.

Other objects will be apparent from the following description and theaccompanying drawings in which a machine formed in accordance with thepresent invention has been disclosed in detail.
